If you have a portfolio of apps, you probably want to cross promote them.

Add this MoreAppsLibrary project(library) as a dependency in the Android Application project you are implementing.
Add the following code in your AndroidManifest.xml:

<activity android:name="com.agiliq.android.moreappslib.MoreAppsActivity"
          android:label="More Apps">
</activity>

Perform an Intent to start the MoreAppsActivity; make sure to putExtra("package", getPackageName());, this ensures that if the your app is in the list of apps being showcased then your app won't be shown.

Intent intent = new Intent(this, MoreAppsActivity.class);
intent.putExtra("package", getPackageName());
startActivity(intent);

You can refer the sample code for a live example.

The data here is the list of icons, the titles and the package names of the apps.
All we do is update the query field in GetAppsDetails class of the GetAppsDetails java app and run this app to get the icons and a string resource xml file.
This xml file contains the titles and package names.
Note: The query string would be the same as what you enter in the search box on Google Play Store.

After you run the java app the data will be saved in the root of that java project.

Move the generated data into the library,
Move all the icons into res/drawable/ and the xml file into res/values/.
